int stdcall YW_UltraLightRead
(
int ReaderID,
int BlockID,
unsigned char *pData);
参数 |

含义 |
ReaderID |
int |
IN |
所要获取的设备标示ID,范围0x0000-0xFFFF,如果未知,则ReaderID=0 |
BlockID |
int |
IN |
起始绝对地址块号 |
pData |
unsigned char * |
OUT |
输出读到的块的数据,16字节,Ultralight一次读出从起始块的4块数据,所以4*4=16 |
返 回 值:大于0为命令发送成功,小于0为命令发送失败
